    SP14 Build Questions Empty SP14 Build Questions

    Hi All!  

    I'm brand new to this forum, and I'm happy to be here and participate.  

    I'm working on a Tubes4Hifi SP14 preamplifier build.  

    I ordered the upgraded Eizz gain controls from Roy. The diamater of  Eizz attenuators threaded shaft behind the selector shaft is too wide for it to pass through the left and right gain holes machined into the front chassis face panel.  Am I missing something?  I would hate to drill right into this face plate to make this work.  But I'm happy to do it if that's what's required.

    I’m curious as to a solution. Any advice/expertise will be appreciated!

    Looks like drilling is in order. Aluminum is very soft, no big deal imo.

    Thank you audiobill!

    I took your advice and all is great. I did have to drill two small additional holes to accommodate the small cylinder-type profusion on the body of the device. All is good!

    Thank you very, very much.
